when scientists refer to the DNA to RNA to proteins pathway, the RNA part of that pathway really represents three different types of rna: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). how is each type of RNA important to protein production

Respuesta :

mRNA is transcribed from DNA and carries information needed for protein synthesis. During the translation phase of protein synthesis, the tRNA carry specific amino acids the the ribosome, and rRNA plays a role in the synthesis of the ribosome which is the site of translation phase of protein synthesis.

The main activity of RNA is to develop proteins through the process of translation. The three RNAs that takes place in the synthesis of proteins are mRNA, rRNA and tRNA.  

• The process of developing the molecules of proteins is known as protein synthesis. In biological terms, it comprises the synthesis of amino acids, translation, transcription, and post-translational events.  

• The mRNA or the messenger RNA is transcribed from DNA and carries information required for the synthesis of protein.  

• At the time of translation, the tRNA or the transfer RNA carry particular amino acids to the ribosome.  

• The rRNA or the ribosomal RNA performs the function in the synthesis of the ribosome, that is, the location where translation process takes place.  

Thus, the three RNAs, that is, mRNA, tRNA and rRNA performs an essential function in the synthesis of proteins.
